CT scans reveal anatomical structures of acupuncture points. This new finding demonstrates the physical existence of acupuncture points. A CT (computerized tomography) scan is a series of X-rays used to create cross-sectional images. In this study published in the Journal of Electron Spectroscopy and Related Phenomena, researchers used in-line phase contrast CT imaging with synchrotron radiation on both non-acupuncture points and acupuncture points. The CT scans revealed clear distinctions between the non-acupuncture point and acupuncture point anatomical structures.

The acupuncture points show a richer microvascular densities as compare to non acupuncture points.
